The current version in repositories doesn't work because was built against fpc 2.4.
I also tried to compile the 0.9.30 version locally with fpc 2.6 but it fails.
At the moment I'm unable to build package that I maintain (skychart).

Wel, the news is that today Lazarus 0.9.30.4 is released. The first release that is build upon Free Pascal 2.6.0. It's not for nothing that it took so long before Free Pascal 2.6.0 was added to Fedora.
I'll add Lazarus 0.9.30.4 to rawhide (btw: 0.9.30.2 is already in Rawhide, compiled with fpc 2.6.0. When it works in rawhide, I'll merge it to F17.

Package lazarus-0.9.30.4-1.fc17:
* should fix your issue,
* was pushed to the Fedora 17 testing repository,
* should be available at your local mirror within two days.
Update it with:
# su -c 'yum update --enablerepo=updates-testing lazarus-0.9.30.4-1.fc17'
as soon as you are able to.
